An equilateral Nb 3 triangle the edges of which are spanned by a BS 4 tetrahedron and bridged by sulfido ligands on the “underside” is found in cluster 1 . The synthesis of this cluster with an unusual electron configuration shows that tetrathioborates can serve as ligands in organometallic chemistry. C p += η 5 ‐EtMe 4 C 5 .
